The auto detect function uses ICMP request/reply packets to test the connectivity of a 
network regularly.

The auto detect function is carried out through detecting groups. A detecting group 
comprises of a group of the IP addresses to be detected. You can examine the 
connectivity of a network by checking the results of detecting groups, which in turn 
enables you to locate network problems in time and take proper measures.

■

Create detecting group 10 on Switch A and add two IP addresses, 10.1.1.4 and 
192.168.2.2, to it to test the reachability to the two IP address.

■

Specify to return reachable as the detecting result if one of the two IP addresses is 
reachable, that is, specify the or keyword for the option command.

■

Set the detecting interval to 60 seconds; the maximum number of retries to 3, and 
the timeout time to 3 seconds.
